For a polished, shiny brilliance, follow the 3 Step Gorilla System below: Used in sequence, the Gorilla System of White, Yellow and Green Pads will turn a dull, rough, scratched stone, marble, granite or concrete floor into a brilliant, shiny polished floor that does not require any wax or other coatings. This new dynamic, low cost method works with your existing floor buffer, scrubber, auto scrubber or high speed burnisher equipment. No need to rent or buy special machines. It really works!Each Gorilla Pad will average about 30,000 square feet of floor coverage before being thrown away. Since many floor restoring applications require up to 10 passes, you may consider that each pad will do about 3,000 square feet of floor. Thats 10 passes over 3,000 square feet for a total usage of 30,000 square feet approximately.
